- Soils under broad-leaved, masson pine, Chinese fir and bamboo forest in the area of Huzhou, Zhejiang were selected for this study. 在我国亚热带采集了常绿阔叶林、马尾松林、杉木林和毛竹林土壤,分析了土壤总有机碳和水溶性有机碳含量。
- Soil total organic carbon(STOC) under broad-leaved and bamboo forest were considerately higher than (P<0.05)those under masson pine and Chinese fir. 结果表明:土壤总有机碳含量常绿阔叶林和毛竹林显著高于杉木林和马尾松林。

- However,subalpine meadow possessed higher species diversity than herb communities within fir forest. 经林线向林外草甸多样性逐渐降低 ,但亚高山草甸仍比岷江冷杉林内草本群落拥有更高的物种多样性。
- The main alpine meadow landscape, mountain rhododendron forest, the original fir forest, herbs and so precious. 主要景观有高山草甸、高山杜鹃林、原始冷杉林、珍贵草药等。
- The main factor of the dynamical change of the ecological forest in Minjiang Watershed was the mutual change among the broadleaf, Chinese fir, pinus massoniana and mixed forest, and there was relatively small change in other types. 闽江流域生态公益林动态变化的主导因素是阔叶树、杉木、马尾松与针阔混交林之间的相互转化,其它森林类型变化相对较小。

- The mechanism of phosphorus mobilization from acidic forest soils under Chinese fir and masson pine by low molecular weight (LMW) organic acid has also been studied with chemical extraction and soil inorganic phosphorus fractionation methods. 并用化学浸提和无机磷分级等方法模拟研究了有机酸对马尾松林和杉木林下酸性森林土壤难溶性磷的活化机制和效果。
- The damage caused by fir decay in alpine fir forest regions of western Sichuan has decreased the outturn rate of the stand and changed the structure of timber assortment. 在四川西部高山冷杉林区,冷杉腐朽病的危害性在于降低了林分出材率、改变了林未材仲结构。
- We examined winter temperature gradients across old growth Douglas fir forest edges and compared these to corresponding summer gradients. 自 1 991年 1 0至 1 992年 5月 ,对林缘至原始花旗松林林内的温度 ,进行了连续的实地测量 ,并与相应的夏季温度变化加以比较。
- It can be found that broad-leaved evergreen forest contained more microbial biomass (MBC) and the ease of oxidation of carbon (EOC) compared with Chinese Fir and Masson Pine stands. 结果表明:常绿阔叶林土壤微生物量碳和易氧化态碳含量高于马尾松与杉木林土壤,杉木林土壤水溶性碳含量相对较低。
- She looked around and padded off across a ravine, toward the edge of the blue spruce and Douglas fir forest that would be her new home. 她环顾了四周一下,便健步越过沟壑,跑向她的新家-一片由蓝色云杉和道格拉斯冷杉组成的丛林。
